ADS-B Dual Reflector Moxon

This is a totally experimental antenna based on an article I saw regarding dual reflector Moxons.  

To construct it you will need the following:

• 6 x small thin cable ties.
• 1 x SMA socket with rectangular base and screw on nut (https://www.amazon.co.uk/dp/B07Z8Z6KBC?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 / https://www.aliexpress.com/item/1005007013777316.html)
• 22AWG/0,5mm^2 Wire

Printing the antenna: 

• I suggest printing vertically with supports.  I used organic supports when printing.  

Constructing the Reflectors. 

1. Take a piece of wire approximate 14cm in length and pass one end through either of the retaining holes on one of the reflector side of the moxon frame and secure it snuggly with a cable tie or superglue.  Cut off any excess wire and trim off the end of the cable tie.
2. Pass the wire through both of the wire retaining loops on the reflector side, making sure it is as taught as it can be, and pass it through the other retaining hole.  Secure that side with another cable tie and trim off the excess.
3. Copy steps 1 and 2 for the other reflector.  

Construction of the receiver and ground side: 

1. Take 2 pieces of wire each about approximately 8 cm in length.  Strip off about 2-3 mm of wire for one end of each wire.
2. Solder one of these wires to the centre pin of the SMA connector and the other wire to any one of the ground pins on the SMA connector.  
3. Pass the barrel of the SMA connector through the large hole, next to the pointer, on the moxon frame and ensure that the retaining nut is properly tightened.
4. Pass the wire attached to the centre post of the SMA connector through one of the loops on frame, making sure it is as taught as it can be, and pass through the retaining hole.  Again secure that with a cable tie or superglue and trim off any excess wire and the loose end of the cable tie.  
5. Pass the wire attached to the ground pin through the only unused loop on the frame and push it through the retaining hole.  Trim off the excess wire and remove the loose end of the cable tie. 

The performance of this antenna is interesting in that when mounted horizontally it picks up local low level traffic (sub 920m ) and then high level stuff (6000m +) but nothing in between.
